NHTSA Complaint #11617210 — 2023 CHEVROLET SUBURBAN 1500

The fitting on the fuel pressure regulator on the engine began to separate from the housing and started spraying fuel all over the firewall and the fuel ran down the firewall onto the exhaust pipes. No check engine light signaled. The only way I knew that it was spraying, was I started to smell raw fuel through the air conditioning vents. Luckily I was able to get it to a dealer before any fuel caught fire. The dealer repaired it but GM stuck me with half of the bill for the repair. I have pictures of the failed part if necessary. This is extremely dangerous to anyone that may not pay attention to car issues unless a check engine light comes on.
